CON-IB'INED REGISTER AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 282,977, dated August14:, 18 83.

' Application filed December 27, 1882. (Ne model.)

To all whom it may concern:

Be it known that I, ABRAHAM 1)..GALLEN- 'rINE,a citizen of the UnitedStates, residing at Marion, in the county of Grant and State of Indiana,have invented a new and useful Combined Register and Ventilator, ofwhich the following is aspecification, reference being had to theaccompanying drawings.

This inventionrelates to combined registers and ventilators, and has forits object to provide a simple, ornamental, inexpensive, and efficientdevice that serves the combinedpun poses of a heating-register, aventilator, and a conductor of light. I

In the drawings, Figure 1 is a face ew of my improved device. Fig. 2 isa transverse; sectional view of the same in position. Fig. 3 is ahorizontal sectional view taken above the lower register. i

- Referring to the drawings, A designates an annular molding, which ispreferably formedfrom a solid block of wood or other material, so thatthere willbe no joints to become separated and otherwise weaken thering, having a circumferential shoulder or flange, B, around its inneredge. This annular molding is to be secured, preferably by screws 0,around a cir cular opening, D, in the ceiling or wall of the room, andthe edge of a cylindrical chamber, E, projects into the molding andrests against E, at itsfront, is arranged a register, F, that alsoprojects against the shoulder B, and at the. rear end of" the chamber isarranged another register, G, that is fitted in a groove or rabbet, H,in the floor above, or in the wall of the adjoining room. The registerscomprise each an annular outer plate, I, formed with slots or openingsJ, and an independent central portion, K, adapted for rotary movementand having about half as many openings or slots L asthe outside ring, I.This sectional construction of register imparts strength anddurabilsections, and the bars between the slots, being shorter, are not.liable to become warped or broken. The interior rotary plate, M, of theregister is formed in one piece, with an outer series of slots oropenings, N, corresponding to the openingsJ in the outer ring, I andwith a central series of openings, 0, corresponding to the openingsL inthe central plate or disk, K. The inner plate,- M, is moved to close theopenings J and L by means of pins or knobs P, that project through and'work in segmental slots QQ in the ring I. The central outer disk, K, ispivoted centrally to the plate M, and may be turned on its pivot B, whenall the opening's J andL are closed, to throw the latter openindependent of the former, by means of an opcrating-knob, S, arranged onthe periphery of the disk K, and is adapted to engage a proj ection, T,on the inner edge of the ring I,to limit movement of the said centralplate.

when used as a ventilator, the chamber E is provided with an opening, U,in its side, which is connected by a pipe or tube, V, with the chimneyor other flue, so that when one of the registers is closed and the otheropened all the foul air, gases, vapors, &c., will pass through the openregister into the chamber E and out edge, the cylindrical chamberprojecting against the said flange and having an opening in its side tobe connected with a flue, aregister at the front end of the chamberresting against the said flange, and aregister arranged at the rearendof the chamber in an adjoining,

room, as set forth.

In testimony that I claim the foregoing as my own I have hereto affiXedmy signature in presence of two witnesses. I
